I'm having some trouble with Illustrator lagging on a new machine. This is a fresh install right off Creative Cloud and I'm using it on this machine for the first time. All the drivers for the GPU and such were just installed as well and are at the most recent version. Illustrator's completely unusable due to the lag though. Every action takes a while to complete. I have time to type a sentence or 2 here in this post while waiting for it to update after hitting the down arrow to bump a shape down a few pixels.
The system is designed for 3D work and burns through 3D simulations in Houdini and video work in DaVinci Resolve. Illustrator should be a walk in the park. I know some people have had issues with dictation on macOS. Could there be something similar going on in Windows 10?
Sorry to hear about the performance issues you are facing with Illustrator. This is not a typical experience with Illustrator. Let us make this right for you. I would request if you can share a few more details like:
Is the issue related to a specific document(s)/asset(s)? If yes, could you please share the document(s)/asset(s) with us? You can upload it to the creative cloud and share the download link.
Did you ever figure out a fix for this? I have a very similar system to yours, but with 2950X & single RTX 2070 and it's been laggy in Illustrator since I got it. Has no issues in other software, just illustrator and I'd love to know why/how to fix it.
